A square of shingles equals 1 bundle. In the roofing industry, a "square" refers to an area of roofing material that is sufficient to cover 100 square feet of roof. Typically, a bundle of shingles is designed to cover 1/3 of a square (or 33.3 square feet). Therefore, three bundles of shingles would equal one square (100 square feet), making option A the correct choice.
